Solution C1-79 (Figure C1.7 condition 9 SM Targ 1988)
The rigid frame, located in the vertical plane (Fig. C1.0-C1.9, Table C1), is fixed at point A hinged, and at point B it is fixed either to the weightless rod BB1 or to the hinged support on the rollers; The rod is attached to the frame and to the fixed support by hinges. A pair of forces with a torque of M = 100 kNm and two forces are acting on the frame, the values, directions and application points of which are indicated in the table (for example, under conditions No. 1, the force F1 = 10 N acts at an angle of 30 ° to the horizontal axis, applied at point K and force F4 = 40 N at an angle of 60 ° to the horizontal axis, applied at point H, etc.). Determine the reactions of bonds at the points A, B, caused by given loads. In the final calculations, take l = 0.5 m.
